* tools: introduce --leak-only memprof parser option

Within this changeset the new Lua module providing post-processing
routines for parsed memory events is introduced:
* memprof/process.lua: post-process the collected events

The changes provide an option showing only heap difference. One can
launch memory profile parser with the introduced option via the
following command:
$ tarantool -e 'require("memprof")(arg)' - --leak-only filename.bin
